Yep - a new version of image spec and distribution spec (not runtime spec).
This version allows for formalized ways to store other types of content in registries (think Helm Charts, OPA policies, etc.), as well as a way to "attach" arbitrary content to registries and then retrieve it later.
Both of these are powerful and will have lots of use cases, but the primary ones at this point are focused on supply chain security - storing content like SBOMs, digital signatures and attestations.
